I'm having eye trouble and Night Light settings does help.
I would like to have it on all the time, but I cannot see how to do the except to set e.g. ON at 8.00 and off at 7.45.
I've not had a whole day to try that yet. Will it work?
PS is there a blue filter app like I have on my phone?

I think if you leave the Schedule "Off", then the
top control works like a light switch, to turn the
effect on immediately or off immediately.

The Windows 10 implementation uses a "fast ramp" to
apply the effect, so it takes maybe ten seconds to
settle to the brown color. The Windows 11 goes
immediately brown, without the shift over ten seconds thing.
(The ramp in Linux is played from a table of 500,000 values,
to give some idea how long the ramp is for cases where it is
applied at sunset. That's how they make it smooth, is use
a lot of values, with tiny tiny shift between each one. That
is what might happen if you used the schedule feature in Windows,
something similar. Playback from a table of values.)
Just don't use the schedule, and it looks like the on-off
thing is a kind of all day setting.
In principle, in the old days the "color temperature setting"
would have done something similar. There were three color temperatures,
and one of them was "correct for Windows" (my Trinitron had three settings).
The gamma on Windows and Mac was different, so if you did photo processing and posted to both platforms, one of the platforms used to complain
"oh, your picture is too dark". In the old days, it was color
temperature which was used as a quick way to alter the blue
content. A high color temperature is blue, a low color temperature
is brown. One brand of monitors, seemed to make all their
screens just a little too blue, as if corporately, they
insisted on a higher color temperature for their products
as a default, compared to competitors. If you had a Spyder
and calibrated the screen, presumably all the screens could
be dragged into doing identical display of content.
You will notice in my screen shots, that the Night Light setting
did not affect screen shots, and the screen shot will record
the blue as it is captured in the original source, rather than
capture the gamma overlay as well. The two squares on the right,
should really have been brownish if the screenshot captured the
screen as actually presented.

I don't use the timed automatic setting, but instead click the
Notifications icon at the far fright of the taskbar, which brings up
a panel of controls ghat includes Night Light. I click to turn it on
or off.
I suspect if you disable the timed on/off of Night Light and then
turn it on manually, it will stay on until you turn it off I do know
for sure that if Night Light is turned on when I shut down, it is
still turned on when I start up again.
